Bryant Vaughn first worked for the USA government as a forensic botanist in 1975, 59 YEARS after pollen analysis was first used by Lennart von Post. L. von Post is considered the father of palynology.
Palynology refers to the discipline that studies plant pollen in both living and fossil forms of life.
Lennart von Post was a naturalist and geologist who is generally regarded as the father of modern palynology.
L. von Post published in 1916 a quantitative analysis of pollen grains entitled “Forest-tree pollen in south-Swedish peat layers”.

The production of orchids by cutting is an example of.
The production of orchids by cutting is an example of vegetative propagation.
There are two methods of growing orchid trees i.e. through seed as well as from vegetative part. Most of the farmers grow orchids plants through vegetative propagation because it takes less time to reach maturity while on the other hand, growing orchids through seed takes more time.
So that's why the farmer prefers vegetative propagation as compared to seed so we can conclude that the production of orchids by cutting is an example of vegetative propagation.

HELP NEEDED ASAP! 30 POINTS AND BRAINLYEST TO WHOEVER ANSWERS WITH THE BEST ANSWER! What are 3 examples of gene therapies that are used to treat diseases?
Answer:
Viruses used in gene therapy are retroviruses, adenoviruses, adeno-associated virus, herpes simplex, and vaccinia. Retroviruses are most commonly used because they can incorporate their genetic material into the host cell’s DNA, thus changing the genetic component of that cell.
Explanation:
Gene therapy is a medical field which focuses on the genetic modification of cells to produce a therapeutic effect or the treatment of disease by repairing or reconstructing defective genetic material. The first attempt at modifying human DNA was performed in 1980 by Martin Cline, but the first successful nuclear gene transfer in humans, approved by the National Institutes of Health, was performed in May 1989. The first therapeutic use of gene transfer as well as the first direct insertion of human DNA into the nuclear genome was performed by French Anderson in a trial starting in September 1990. It is thought to be able to cure many genetic disorders or treat them over time.

with either brown or blue eyes. Remember to use complete sentences and correct
grammar.
Answer:
Brown eyes are a dominant trait.
Explanation:
Brown eyes are a dominant trait, and blue eyes are a recessive trait. If the father has brown eyes, they can have either a BB or Bb genotype; the mother must have a bb genotype in order for her eyes to be blue.
Refer to the Punnett Square below to see how it's possible for this mother and father to produce children with both colored eyes.

Although the human colon may be one of the most diverse microbial communities on Earth, the majority of the bacteria are classified as __________.
Answer:
prokaryotic bacteria/cells are found to be the most common type of single organisms.
Although the human colon may be one of the most diverse microbial communities on Earth, the majority of the bacteria are classified as anaerobes.
What are anaerobic organisms?Anaerobic organisms are life forms that generate ATP in hypoxia conditions (absence of oxygen).
ATP is the energy con of the cell to carry out different cellular metabolic functions.Anaerobic bacteria form part of the intestinal microflora in humans.In conclusion, although the human colon may be one of the most diverse microbial communities on Earth, the majority of the bacteria are classified as anaerobes.

The mitochondria are defective and do not produce sufficient protein to synthesize microtubules in the cilia and flagella.
Answer:
The mitochondria are defective and do not produce sufficient protein to synthesize microtubules in the cilia and flagella. The plasma membrane of the alveoli is not permeable to carbon dioxide during respiration because it is too hydrophobic. The cells do not produce functional motor proteins in flagella and cilia.

The world population has surpassed 7 billion and is continuing to increase dramatically. Select the factor that has demonstrated an
inverse relationship to population growth.
es )
A)
deforestation
B)
violent political conflict
spread of communicable diseases
D)
biodiversity of plant and animal species
Answer:
D
Explanation:
As population grows all the above factors increase expect the biodiversity of animal and plant species.
On a basic level, it is obvious that population increase and per capita income growth are related. Per capita income is simply total income divided by the population. Thus, option D is correct.
What inverse relationship to population growth?When attempting to forecast changes in population size, demographers frequently focus on four essential criteria.
The population's starting age profile (whether it is relatively young or old to begin with), migration, and fertility rates (death rates; life expectancy).
Depending on particular environmental factors, two different patterns of population expansion may manifest: In a perfect, limitless environment, an exponential growth pattern (J curve) manifests itself.
The development of a logistic growth pattern (S curve) occurs when external forces reduce the pace of growth.
Therefore, The gap between the growth rates of income and population is roughly equivalent to the growth rate of per capita income.

Can an objects mechanical energy be equal to its gravitational potential energy?
Answer:
Yes
Explanation:
Because if an object falls, it gives up its gravitational potential energy. The gravitational force does work on it, and speeds it up.
Answer:
yes
Explanation:
if an object does not have kinetic energy, meaning, it is not moving, its mechanical energy would be equal to its gravitational energy.
